"We are satisfied at the tribunal's decision, which was taken on solid evidence and we hope with this decision the image of the game will improve," Lorgat told a press conference in Doha.

Lorgat, who was accompanied by the head of the ICC's Anti-Corruption and Security Unit (ACSU), Ronnie Flanagan, was speaking a day after Butt, Aamer and Asif were handed lengthy bans for spot-fixing.

Butt was banned for 10 years, with five years suspended, while Asif and Aamer were handed bans of seven years with two suspended and five years respectively.

The charges relate to alleged incidents during the Test against England at Lord's last year, when Britain's News of the World newspaper claimed the players were willing to deliberately bowl no-balls.

The newspaper alleged the three had colluded in a spot-fixing betting scam organised by British-based agent Mazhar Majeed.

In a separate development on Friday, British prosecutors charged the three players as well as Majeed with corruption offences and summoned them to appear in a London court on March 17.

The trio have repeatedly denied wrongdoing.

Lorgat rejected the suggestion that the punishments were lenient.

"I don't believe the sentences are lenient by any stretch of the imagination," said Lorgat. "I think they are balanced with an expert and experienced jury dealing with the case."

The three-man tribunal was headed by Michael Beloff QC and also contained Albie Sachs of South Africa and Sharad Rao of Kenya.

"In legal terms you have to be proportionate when you are giving punishment and we must distinguish between match-fixing and spot-fixing, and the jury was independent and they decided on proportionate punishments," said Lorgat.

Lorgat said the verdict will send a clear message to the cricket world.

"While I am deeply saddened that this case happened in the first place, I acknowledge and commend the decision to deliver lengthy bans to all three players.

"Corruption in our game will never be tolerated and, once again, I reiterate our zero-tolerance approach. I hope this investigation, and the verdicts delivered, makes that message crystal-clear."

Butt and Aamer have expressed disappointment at the bans, with Butt hoping to get the ban reduced once the ICC code of conduct -- which carries a mimimum five-year punishment -- is amended.

Lorgat said the case tarnished the reputation of the game.

"We now would hope that the reputation, after having been initially tarnished, is now safeguarded. This is the incident we do not want to see in the game and equally at the speed at which we brought forward the charges, show our seriousness and we will do everything necesssary to protest the integrity of the game."

Lorgat said both the players and the ICC have the right to appeal.

"If they wish to appeal, its their right. We haven't considered that (appeal) at this point," said Lorgat, who said any suggestions to root out corruption are always welcomed.

"The ICC Board has open mind and we are ready to listen all suggestions in order to root out corruption from the game, we consider all the recommendations that come our way," said Lorgat.

Flanagan, who took over from Lord Paul Condon last year, also showed satisfaction over the proceedings.

"Over the past few months, the ACSU and the ICC's legal team have worked extremely hard on this case, including in its investigations prior to the time that the News Of The World's story broke.

"We have subsequently received significant support and cooperation from the newspaper's investigators and the Metropolitan Police in order to develop the evidence on which the tribunal has based its decision.

"This case gives us a platform to build on and carry on our fight," said Flanagan.
